WG103 Angle Sensor for XCMG Crane Boom Systems
The WG103 angle sensor measures boom or structural angle in compatible XCMG crane monitoring systems. Its signal supports geometry calculation and safety monitoring, so mounting orientation, electrical interface and calibration must be correct.
Identification and Matching
Model WG103 and complete label
Crane and LMI system model
Connector type, pin count and cable length
Mounting-hole pattern and reference orientation
Signal specification and calibration procedure
Application and Service Scenarios
The sensor may be investigated when angle data is missing, unstable, fixed at one value or inconsistent with physical boom position. Wiring damage, supply voltage, connector corrosion, mechanical looseness and incorrect calibration can cause the same symptoms.
Inspection and Installation
Secure the boom and disconnect power as required. Install in the original orientation without forcing the shaft or housing. Protect the cable, then perform zero/reference calibration and compare displayed angle with an approved independent measurement through several positions.
Frequently Asked Questions
Can WG103 fit every XCMG crane?
No. Mechanical, electrical and LMI compatibility must be verified.
Does an incorrect angle reading prove sensor failure?
No. Mounting, wiring, voltage and calibration should be checked.
Is calibration required after replacement?
A reference or calibration procedure is commonly required for safe operation.
Export Packing
The sensor body, connector and cable are cushioned and moisture-protected, with WG103 clearly marked.
